  New version for Delphi 2009 and CL32.DLL Version 3.4.0

This version has been tested with Delphi 2009 only, I have no newer Delphi versions available and do not intend to buy one!

I do not support Visual Basic any more, a cryptlib.bas for older Visual Basic versions is contained in Peter Gutmans release 3.4.2

Cryptlib version 3.4.0 introduced new and changed several constants.

• New version of DelphiCryptlib.pas
  
• New versions of cryptlib.pas for Cryptlib version 3.4.0
  
• Changes in some source files in DelphiSamples.zip
• Changes in Cryptlib Spy:
  New version for Delphi 2009 and CL32.DLL Version 3.4.0

This version has been tested with Delphi 2009 only, I have no newer Delphi versions available and do not intend to by one!

I do not support Visual Basic any more, a cryptlib.bas for older Visual Basic versions is contained in Peter Gutmans release 3.4.0

Delphi 2009 introduces a new string handling. AnsiString and PAnsiChar now play the role of string and PChar in previous Delphi.

Modifications were necessary in almost all Delphi sources. This new version is now compatible with Delphi Versions Delphi 2005 and Delphi 2009. Other versions should run as well, but I could not test any other version of Delphi.

  solves a problem in envelope handling for compressed and envelope only files

• New version of CL32.DLL from Peter Gutman's development snapshot version
  solves a problem in envelope handling for compressed files

This version solves a problem in cl32.dll V3.3 concerning compression of big files in an envelope. Use this library if you get errorcode -15 ( = Operation failed ) when de-enveloping a big (>15KB) file. The compression is wrong, but the problem is detected on decompression!
